Washington, D.C. 1885. unbound. Rare assemblage of three documents pertaining to the founding, completion, and dedication of the Washington Monument. First is the original ornate August 1, 1850 subscription mailing letter titled "The Officers and Board of Managers of the Washington National Monument Society." 1 page measuring 10.5 x 8.25 inches, with 19 facsimile signatures of the officers including Millard Fillmore as ex-officio President and Winfield Scott and Peter Force as Managers. A vignette of the original design of the Washington Monument is at the upper left. The next item is an outstanding example of the U.S. Government invitation to attend the Ceremonies on the Completion of the Washington Monument; heavy stock with no folding creases. Measures 10.25 x 6.75 inches. In full: "The Capital, Washington, D.C. The Commission appointed under the joint resolution of Congress approved May 13th 1884, in relation to ceremonies to be authorized...at the dedication of the Washington Monument...requests the pleasure of your attendance at these ceremonies to be held in the City of Washington, D.C. on February 21st 1885." Signed by John Sherman, Chairman of the Commission. Decorated with an excellent steel engraving of Gilbert Stuarts depiction of George Washington; with flags, rays of light and images of liberty surrounding the monument. The invitation is hand-addressed to Madison Davis -- Post Office Dept. -- an African-American Postmaster appointed in Athens, Georgia on February 13, 1882.The last item is the very elusive ticket to attend the Dedication of the Washington Monument, February 21, 1885, on the Floor of the House of Representatives: "Admit bearer to the East Door leading to the Rotunda." Signed by John Sherman (in facsimile) as Chairman. This rare example has one tiny chip at the lower border and some foxing on the word "Dedication." Three years after the dedication, when the Washington Monument finally opened to the public (October 9, 1888) it was hailed as the "Worlds Tallest Structure." The first two items are in very good(+) condition; the last is very good(-).
